In the utility model structure, rectangle stainless steel tube, anchoring piece, FRP spiral bars all have corrosion resistance, are straight
It connects to gather materials using sea sand and the possibility of seawater marine sand concrete raising reality is poured with seawater preparation；FRP spiral bars have excellent
Tensile property, effective restraining force can be provided for core concrete, but its connection with rectangle stainless steel tube is technology
Key, the utility model is by setting anchoring piece, and by the gap between FRP spiral bars and the reserving hole inside of anchoring piece
Seawater marine sand concrete is filled, the cushion pad between FRP spiral bars and anchoring piece is formed, avoids FRP spiral bars and rectangle stainless
Stress concentration at fastener for connection；Rectangle stainless steel tube inherently have certain rigidity, can as the template of casting concrete,
And the vertical load in work progress is undertaken, FRP spiral bars can strengthen the binding effect to core concrete, especially strengthen
Concrete constraint in the middle part of the pair cross-section length of side.More than characteristic can make the utility model structure be widely used in coastal engineering,
The construction such as ocean engineering.
The utility model overcomes well known common steel tube concrete structure and normal spiral stirrup concrete filled steel tube
The defects of existing, has the advantages that：
(1) traditional fresh water river sand gathering materials as concrete is replaced using seawater sea sand, alleviates fresh water, river sand money significantly
The problem of source is in short supply.
(2) anchoring piece of reserving hole completes good power transmission between FRP spiral bars and rectangle stainless steel tube so that FRP
Material and the two different materials of stainless steel material can be common work, FRP spiral bars constrain jointly with rectangle stainless steel tube
On core coagulation.
(3) have the characteristics that high capacity, ductility are good, durability is good.
